PARADISE VALLEY, Ariz. — Major League Baseball will test for human growth hormone throughout the regular season and increase efforts to detect abnormal levels of testosterone.

Players were subject to blood testing for HGH during spring training last year, and Thursday’s agreement between management and the players’ association expands that throughout the season. Those are in addition to urine tests for other performance-enhancing drugs.

Under the changes to baseball’s drug agreement, the World Anti-Doping Agency laboratory in Laval, Quebec, will keep records of each player, including his baseline ratio of testosterone to epitestosterone, and will conduct Carbon Isotope Ratio Mass Spectrometry (IRMS) tests of any urine specimens that “vary materially.”

“This is a proud and a great day for baseball,” commissioner Bud Selig said following two days of owners’ meetings. “We’ll continue to be a leader in this field and do what we have to do.”

The announcement came one day after steroid-tainted stars Barry Bonds, Roger Clemens and Sammy Sosa failed to gain election to the Hall of Fame in their first year of eligibility.

Commenting on the timing, Selig noted the drug program changes had long been in the works “but it wasn’t too bad, was it?”

Clemson receiver Hopkins heading to the NFL

CLEMSON, S.C. — Clemson record-setting receiver DeAndre Hopkins is heading to the NFL and skipping his final season of college.

Hopkins said on Twitter on Thursday that while he enjoyed his time with the Tigers, he is ready for the next level. Clemson athletics spokesman Tim Bourret confirmed that Hopkins is making himself eligible for the NFL draft in April.

Hopkins set single season school records with 1,408 yards on 82 catches, and his 18 touchdown grabs were an ACC record.

On Wednesday, ACC player of the year Tajh Boyd declared he would return for his final season at quarterback for Clemson.
